STMicroelectronics AN2691 Application Note RPD Pin Functionality
This document details the dual-purpose functionality of the Return-from-Power-Down (RPD) pin on ST10F27x and ST10R27x microcontrollers. It describes how the RPD pin distinguishes between asynchronous and synchronous reset events based on signal timing and level, ensuring proper system startup behavior.

Questions answered in these manuals
What is the minimum duration an RSTIN pulse must exceed to trigger an asynchronous reset when an RC network is connected?
An RSTIN pulse must be longer than 10 ms to force the device into an asynchronous reset.
From: STMicroelectronics AN2691 Application Note RPD Pin Functionality
How long does the internal weak pull-down device discharge the external capacitor at a typical rate?
The internal pull-down device discharges the external capacitor at a typical rate of 100 to 200 pA.
From: STMicroelectronics AN2691 Application Note RPD Pin Functionality
What specific conditions trigger error interrupts?
Error interrupts occur when warning status indicates error counters have reached the limit or when the controller enters a bus-off state.
From: STMicroelectronics AN2628 ST10F27x CAN Interrupt Drivers Programming Application Note
How are message-specific interrupts individually enabled?
These interrupts are enabled by setting bit TXIE for transmission or RXIE for reception in the CAN message objects.

What are the two types of oscillators available in ST10F27x devices?
The devices implement either a Wide-swing oscillator (for models ending in E) or a Low-power oscillator (for models ending in E/B).
How does the start-up time of a ceramic resonator compare to a crystal?
Ceramic resonators have a much shorter start-up time than crystals, being about 100 times faster.
